Quite often we get this query from our evaluators and customers. We already have this data exposed in the OpManager knowledgebase; however I thought it would be nice to do a blog on it as well.
To analyze bandwidth consumption, we ran OpManager in an isolated environment and monitored the devices as listed below
- 100 Servers (includes service monitoring like Web, MySQL, FTP, SMTP, HTTPS)
- 3 Switches (each had 24 Ports).
- 3 Routers (each had 5 Interfaces).
- 2 Firewalls (each had 3 interfaces).
- 2 Printers
Servers are monitored through WMI with default monitors (CPU, Memory & Disk) associated.
Monitors like CPU, Memory and Interfaces Rx & Tx Traffic/ Utilization/ Errors/ Discards are associated to Network Devices (like Switches, Routers, Printers and Firewalls) by default.
Monitoring Interval is set to 1 minute for all monitors and the status polling is also set to 1 minute.
Here is the report for you…
UDP Traffic: 5225 bps
TCP/ WMI Traffic: 39435 bps
ICMP Traffic: 1980 bps (18 bps per device)
So, OpManager generates a total traffic of approximately 47Kbps within the LAN in order to monitor 100 Servers, 3 Routers, 3 Switches, 2 Firewalls and 2 Printers.
Hope you find this information useful.
One more info…Recently, we brought out a new SNMP tutorial for beginners. Do check out the animated gifs to explain SNMP communication for various commands like GET, TRAP and INFORM.
